My Lathe Restoration

[@hovensjan]

Hi, You might be interested. Your lathe is a so called "patronendrehbank" made by de firm Kröner und Reimer Leipzig Lindenau. She is modified. The ballbearing in the back is not original. Originally the spindel can move lenghtwise in smooth bearings. This movement was possible by a so called star wheel and threaded bushes with different threads ( patronen auf deutsch). All of this so you could cut screw threads on this lathe. I think I saw some parts of the mechanism in the original video but it looks like You did not use it in the restoration. I myself got 2 of these lathes ( all be it incomplete) and found a picture of this late in: " Paul Schlichting Die Feinmmechanik" . Congrats, nice work. Jan

[@Rolingmetal]

Nothing about Kroner and Reimer on lathes.co.uk so there's a noble job for you :) Looks a lot like the old Karger lathe I'm fixing up.

[@dj1NM3]

To cut threads on a lathe, there needs to be a lengthwise drive-screw for the cross-slide. The cross-slide drive and the main spindle are geared together, so that as the chuck turns the cross-slide advances, to create a thread. What you described (the spindle with the chuck moving backwards and forwards) sounds more like a "rose lathe" or "rose engine", used to create guilloche patterns and uses those "star wheels" to control the movement of the main spindle.

[@Rolingmetal]

I'm sorry Jeff but in this case you are wrong. Have a look at this: kzbin.info/www/bejne/a5CzhHafi56rbbM

[@TechGorilla1987]

+Rolingmetal - That was a great video. Very interesting.

[@Martin-pb7ts]

Love seeing an old machine like that come back to life.

[@jcpopvinyl1228]

I've become addicted to watching your videos I found this channel 3 days ago and I think I've watched like 20 videos already

[@apistosig4173]

That lathe is nothing short of a piece of Art - stunning restoration

[@MegaAndroyd]

"Hello friends" is my favourite part of your channel.

[@Wingnut_Stickman]

the pair of intermediate pulleys is called a "jack shaft" and they are often used in power transmission to attain precise ratios, or in cases where side load is not desirable and face mounting is impractical.

[@kiwingenuitynz7799]

I am restoring a Seneca lathe at the moment almost the same age - great job on your arduous clean and build. I am considering mounting a 3 phase motor and VFD also for speed control and improved safety, but am still considering the belt slip with the original design that reduces the shock load to the chuck and headstock bearings. If anyone else more familiar with this aspect has experience please leave a comment :)

[@abettermousetrap]

Very cool and well done. It's really nice to see you bringing back these old pieces from the boneyard. Thanks. Keep up the great work and videos

[@mtmchenry]

Nice job restoring it and getting it running.

[@MRrwmac]

That was a wonderful old lathe with signs of many years of hard work! Now, due to you great restoration, it will have new life as an excellent machine again! I’m sure the lathe is overjoyed and excited to get to work with some humans again!

[@cackleberryfarm4598]

MAN! That thing looks gorgeous !!!!

[@andyash5675]

The intermediate shaft between the motor and the spindle is known in the UK as a "layshaft". The overhead drive and belt system is known as a "lineshaft".

[@andyash5675]

The mounting system that supports the layshaft and lineshaft is known as a plummer block.

[@38911bytefree]

Nice lathe restoration. Yep, this thing are a work of art ....

[@MilanDupal]

You gave a new life to old beauty. Thanks for her and your post.

[@SpatialGuy77]

Wow, you are doing a fantastic job with that lathe - congratulations, it looks terrific. It most certainly will be the first time that lathe has seen a carbide insert, lol, or an aluminium bar for that matter. Lol, well done.

[@Xynudu]

Nice lathe restoration. I did up an old Schaublin 102 toolmakers lathe in way worse condition and it also came up a treat. Those old lathes certainly have style. Plus they are nice to use, quiet etc. Cheers Rob

[@lyntoncox7880]

Great restoration and a testimony to its build quality and also former owners, that it still, despite the vibration, runs so well. The chuck came up particularly well I thought and the whole seems a very useful machine still. Well done!

[@edgeeffect]

I remember back when you go this... it was one of the events that made me go out and get an old lathe of my own. It's good to see if working, I thought you might have hit some kind of disastrous "wall"... and that's why we heard no more.

[@Spoif]

To get a nice true thread, it might be a good idea to lead the tap into the work-piece whilst holding it flush, against the headstock; then feed by rotating the chuck.

[@kfjfjfjewlsls]

Found this channel when this project was started, kinda nice to see it completed :)

[@EngineersWorkshop]

That's a really nice lathe you have! I love old equipment for it's ruggedness and style.

[@jeffryblackmon4846]

Very nice. The before and after photos represent a lot of work.

[@shurlin79]

just in time :) I bought the same kind of belt driven german lathe (Kärger) a couple weeks ago. Will try to restore it this spring

[@ronyerke9250]

English words for that intermediate shaft are Jackshaft or Countershaft. The difference is which direction the shaft rotates. Automotive transmissions use gear driven countershafts that reverse rotation to transmit movement. What you used is most likely a jackshaft as it rotates in the same direction as the motor and the chuck. I just looked it up.

[@jamesmauer7398]

Nice restoration, and video capturing it. The lathe looks great.

[@bj20715]

Looks like it came out great. Bit of fine tuning and it should make reasonably round things!

[@prmicrotech]

You Sir are a BAD ASS!!! Fantastic Job!! You should be very proud of the work you do... I'm almost at a loss for words... Excellent!!

[@gizmothewytchdoktor1049]

it's a "transmission drive" from previous other references . was probably done in the late forties. i offer this because i have seen this type of setup/modification several times and they were claimed to have been done around that time frame. folks used what was at hand to get things done and this type of drive was tried and true at the time. of note i have seen similar setups that used small gasoline engines. very sketchy! i enjoyed seeing it brought back to life.

[@horacerumpole6912]

No, it's a jackshaft-used to subdivide rpm from motor and increase torque.

[@KnightsWithoutATable]

You should also build a cover over the pulleys to keep things from getting caught. Thin sheet metal or expanded steel would work just fine.

[@lv_woodturner3899]

Very good work on the restoration. Well done. Looks to be in very good shape now. I can appreciate you are glad the restoration work is behind you and the lathe finally up and running. I did some cleaning of a Southbend Heavy 10 back in 2014. A lot of work, but your restoration was even more work. The lathe may have been designed for line shaft drive, the picture you showed with the large overhead flat belt pulleys. Originally the line shaft may have been driven by a water wheel, later a steam engine. I would refer to your present drive system as using an intermediate drive shaft. Very common for old lathes which were designed for line shaft drive which was much slower speed than an electric motor. Your tool post design needs shims to get the tool at centre height. Consider getting feeler gauge sets at a flea market and take them apart to provide a lot of shims of different thickness. Not good that the pulley is causing vibration. This could impact the finish on the machined parts. You would need another metal lathe to try and fix the imbalance, unless you can add weights similar to car wheel weights. Dave.

[@tabcreedence6553]

Great videos. May I suggest Soda Blasting for cleaning off that paint, leaving behind a water soluble media. I use a gun with the little media tank on top or you could use almost any kind of blasting system.

[@JohnDoe-pv2iu]

A needle scaler is great for slag cleanup after stick welding. Great video! Take Care and be safe, John PS, you know, I guess that belt drive setup could be called dangerous but I don't think it is any more dangerous than the inherent 'danger' of operating a lathe. In other words, if the belt drive is too dangerous for the operator, then they shouldn't be using a lathe in the first place.

[@chuirios365]

Nice restoration, you did a wonderful job! I just finished restoring a 1903 Stark flat belt lathe, it was in about the same condition. I'm a retired toolmaker, from California, hope to chat someday!

[@mcorrade]

wow that "needle scaler" was something I had never heard of. I just looked it up and its a great tool!!!

[@velwheel3135]

The intermediate pulley assembly between the motor and headstock is called a jack shaft.

[@CraftedChannel]

The assembly in English is called a counter shaft. The counter shaft assembly actually looks very good and is standard on lathes 50 years newer. The only thing I would change is rounding corners of the flat plate just to blend their style in with the other curvy/cast parts. Looks like a great vintage lathe. Your lathe was a Treadle or foot power lathe in the beginning I bet. In the end there is little consideration for antique value. It's mostly about functionality. Put a quick change tool post on it and don't look back.

[@aguilayserpiente]

Good cinematography and narration. Mechanic soap, oil eater aka simply orange, etc, are good degreasers.

[@Yhrim70]

Nice Job. Have wanted a lathe for many years... might happen sometime. Citric Acid for rust removal works Great! I always keep a stock of citric acid in the shop.

[@allyouneed71]

Looks Great. I agree, those belts have got to go. I'm looking forward to your upgrades.

[@donstewart2059]

I think the lathe always need the belt drive set-up not direct drive

[@TradeWorks_Construction]

I don't think English as specific term for the motor setup however we would refer to the shaft and pulley assembly driven by the electric motor as the countershaft assembly, which is always paired to a matching "driveshaft/transmission" or in this case the spindle. Little late on the feedback ... but who knows.

[@BernhardHofmann]

If the Jacobs Chuck is only held in the tailstock by the friction of the Morse taper, you should hold the chuck when reversing out of the hole you drilled. The last thing you need is a chuck (and drill) being flung at speed randomly across the garage, possibly in your direction.

[@isidoromaich7226]

Your restoration turned out well 😉

[@senorjp21]

Beautiful job

[@MrLukealbanese]

In Eglish, we call this overhead belt power supply was known as 'lineshafting'. Great video.

[@tiger12506]

I don't know if there is a specific English name for that intermediary pulley shaft, I think I would just refer to it using the generic name "jackshaft"

[@WatchWesWork]

Counter shaft

[@transdimensionalist]

yes counter shaft, and bit motor sits on is motor mount/bracket

[@yannkitson116]

Counter shaft is used for gear transmissions because the rotation is reversed. Intermediate shaft is the term when pulleys/chains/belts are used because they do not reverse the rotation.

[@transdimensionalist]

'jack' mayb more technically correct but if you search ebay for lathe parts you find nothing for jack shaft and everyone refers to the shaft in question as a counter shaft www.ebay.co.uk/sch/i.html?_from=R40&_sacat=0&_nkw=lathe+countershaft&_blrs=spell_check

[@gillianst-claire176]

[@AirborneSurfer]

Beautiful restoration!

[@demagmusic]

When using a sand blaster on delicate automotive items (sheet metal) people often use ground walnut shell. Maybe a softer blasting media would be suitable for some of your moving parts, threads? I would experiment on something non-valuable, of course ;) I just HATE using chemicals, personally.

[@twocvbloke]

I'd call that bit with the belts and pulleys on a transmission, as it's transmitting the power from the motor through itself (and looks like you can "change gear" too with it) to the lathe, probably a proper English word for it, but I don't know what it might be... :)

[@michaeldenton8610]

We call it a thing! I would enjoy videos of you modernizing the drive of the lathe and adding some functions not available in its current state

[@noweare1]

Purrs like a kitten, great job. That's a lot of work !

[@richardharries5551]

I've always called the left side where the variable pulleys connect to the chuck The HEADSTOCK. The opposite is the tail stock....

[@aklef]

I'm excited for the upcoming welder! Cheers

[@sofoclispetrosjulyan1397]

Better lathe than never

[@hillbillynick2000]

The part is called a jackshaft in English. Nice lathe!

[@snafu21]

I've always heard intermediary pullies called "Jackshafts"

[@stemer1149]

Great video, very much enjoyed it, thank you for showing. As you mentioned adding a VFD for the motor, I was wondering how you would size it (wattage or full load current). I have a similiar old lathe, it too was converted from overhead drive to direct motor drive. The motor mounted is a Brown Boveri 1.3kW. However, that might just have been any motor they had available and might be oversized, or not. So, for selecting a VFD I was wondering how much headroom to give for lathe operation, ie 2.2kW or 3kW. I will need to run it on single phase 230V and wire the motor for 230V 3-phase (Dreiecksschaltung). And therefore was wondering, what motor you have and how big a VFD you would pick..

[@1959Berre]

Congratulations on the restaration of your lathe. Looks fine. Have a lot of fun with it. (Gratuliere! Viel Spaß damit, sieht ausgezeignet aus.)

[@chiperchap]

Wow it was great to see it brought together :) I've wondered when that'll be the project of the day :) I know it's not really your thing but I'd love to see how you'd approach making a 12v dc oven as I'm living off grid with low income so either fix it modify it or build it :) not a fan of new lol Andy

[@ralph9987]

i am curious to hear your thoughts on the best way to protect steel from rusting in salty environments. i am torn between cold bluing and or then oxide etching primer and then a 2pac paint?? danke im voraus

Thank you very much for the quality content.

[@tanveerahanger8724]

Amazingly talented guy love your work keep going on and keep doing what you love to do

[@zafaradil3548]

Great restoration.tell us what is "accuracy" of this lathe?Good,bad or acceptable.

[@imchris5000]

that belt system is not that bad and you can easily make some guards out of sheet metal

[@sacriptex5870]

finally at last! my beard grew waiting that video.... i almost travelled to germany to help you man!

[@cojones8518]

www.lathes.co.uk/auerbach/ Maybe the company that made your lathe? Definitely a German design I'd leave the intermediate pulleys as they are. It's a good system and if it isn't broke why fix it and the guy that converted it did a good job. English name for it is Countershaft. Countershaft is also a generic name for any gear or pulley shaft that transfers power to another gear train or pulleys. The common English name for the belt system at 6:50 is _Line Shafting_ There's a series of pulleys on a common shaft that is driven by a steam engine. Check out David Richard's channel kzbin.info/door/Bdj-vOveiEFWe3vnGoJUag He runs his entire machine shop with line shaft and a steam engine.

[@Roy_Tellason]

My grandfather had some of that stuff in his workshop...

[@stoatrepublic]

7:50 I would call this the Primary Belt Drive or Live Drive (motor to Intermediate shaft) my English is not good, but I did work at the Poreba Machine Tool Factory in Poland about 10 or 11 years ago.

[@osamahnajjar2824]

Nice work! But I don't think using a motor with a speed controller is the best idea since the motor's output power depends on its speed and it can give its maximum power while its is running on maximum speed only, which means that the lathe may find troubles turning bigger diameters which requires very slow speed!, the solution is to use a gearbox, I believe that your creative mind can combine a gearbox from an old bike's motor with the lathe!?

[@FreeOfFantasy]

no he should not pull more then designed torque out of the motor as he can burn out the coils otherwise. Also at very low speeds a independent forced air cooling may be necessary.

[@mealex303]

What's the deepest cut you can take on steel with belts with this ? Great resoration

[@HaasMill]

It is interesting how were made rotary parts of the first machine tools in the world without using any machine

[@DougHanchard]

Very nice restoration!

[@74rrj]

Congratulations what a wonderful work thank you for posted.

[@porkycrook]

Top job young sir.

[@stephensimpson5283]

Is it just me or does the chuck move backwards when you are drilling? Maybe a bearing is worn and allows movement away from the tail stock? Brilliant job. Love old tools being resurrected.

[@l3p3]

Das schreit irgendwie danach, mit dem "Roboter"-Projekt in Verbindung gebracht zu werden und eine CNC-Maschine daraus zu kreieren. Die 3D-Drucker-Lobby kann etwas Gegenwind gebrauchen.

Envy you for that lathe mate. It represents an era and it's good enough in many applications. Do you know what year was it made and who was the manufacturer?

[@gureidens61]

TPAI, what you think about removing rust with a phosphatizing agent? I tried the gel citric acid one with little success.

[@terryholdredge6393]

Brilliant restoration. That said, please reconsider the use of gasoline as a solvent. Its explosive properties make it suitable for internal combustion engines only. Thank you!

[@U_Kamrc]

I like your soft style of narration (with big English vocabulary). Am not yet that far (w/ English).

[@Landrew0]

Yes, good English. Very understandable. Still a few consonants are being slightly transposed between hard and soft, but not annoyingly so. i.e. "F""V," "B""P," "Couple""Cobble"
